Data Tampering Protection

Definition ∞ Data tampering protection guards digital information from being changed without permission. This refers to the security mechanisms implemented to prevent unauthorized alteration, deletion, or corruption of data, thereby maintaining its integrity and authenticity. In blockchain technology, cryptographic hashing and distributed ledger architecture inherently provide robust data tampering protection. Each block contains a cryptographic hash of the previous block, creating an unchangeable chain of records.
Context ∞ Data tampering protection is a foundational security property of blockchain systems, frequently highlighted in news regarding the trustworthiness and immutability of digital assets. Discussions often center on the resilience of various consensus mechanisms against attempts to falsify transaction histories. Ongoing research seeks to fortify these protections further against advanced computational threats and quantum computing risks.
